Thermal ablation is heating tumors so hot that the tumor cells die. It has been studied in many forms, including microwave, laser, high-intensity focused ultrasound, and cryotherapy (freezing below -20 C). Radiofrequency thermal ablation or radiofrequency ablation (RFA) has emerged as the most commonly used technology for thermal ablation in the bone, liver, kidney, lung, heart, breast, lymph nodes, nerve ganglia, and soft tissue.
New surgical procedures are being developed that could help to speed healing time and reduce pain for adult patients suffering from chronic tonsillitis.
When out-of-control nerve impulses cause the heart to beat irregularly, cardiologists often use heat during a minimally invasive outpatient procedure to destroy the defective signaling pathways and restore the rhythm to order.
A relatively new, minimally invasive treatment was 100 percent successful in eradicating small malignant kidney tumors in a study of more than 100 patients, report researchers from Wake Forest University Baptist Medical Center.
Multiple-electrode radiofrequency ablation is a safe and effective way of treating patients with liver cancer that can be completed in less time than current ablation techniques, according to a recent study conducted by researchers at the University of Wisconsin in Madison.
The use of concentrated radio waves appears to be a safe and effective way to "burn" away abnormal cell growth in the esophagus that can be a precursor of cancer.
Percutaneous imaging guided radiofrequency ablation (RFA) of hepatocellular carcinoma is a safe and effective technique, with benefits such as reduced post-procedural pain and length of hospital stay, according to a study conducted by researchers from Changi General Hospital in Singapore.
Researchers from the three University of Texas campuses in the Dallas-Fort Worth metropolitan area are combining their expertise in biomedical science, engineering and physical sciences on projects aimed at solving real-world medical problems.
A minimally invasive procedure known as radiofrequency (RF) ablation is effective for treating lung cancer in patients who are not candidates for surgery, according to a Rhode Island Hospital study published in the April issue of the journal Radiology.
Mayo Clinic researchers report that freezing kidney tumors through percutaneous cryoablation shows promise for patients who are not good candidates for surgery.
Energy ablative strategies (percutaneous and laparoscopic) are being increasingly employed in the treatment of small renal masses.
As many as 3 percent of all pregnancies result in the birth of a baby with chromosomal anomalies like Down syndrome or structural anomalies such as congenital heart disease.
Three-year data shows that radiofrequency ablation is as effective as surgical resection for overall survival and tumor recurrence, for the treatment of single small hepatocellular carcinoma in patients with liver cirrhosis, according to a study presented at the Society of Interventional Radiology's 31st Annual Scientific Meeting.
The U.S. Food and Drug Administration (FDA) today approved an innovative combination of technologies that will enhance a doctors' ability to treat patients with abnormal heart rhythms (cardiac arrhythmias).
Massachusetts General Hospital (MGH) researchers have shown that radiofrequency ablation (RFA) - a minimally invasive way of destroying tissue - is an effective, longlasting treatment for small kidney tumors in selected patients.
The use of expandable electrodes with multiple tips in the treatment of liver tumors by radiofrequency ablation (RFA) is safe and effective, making it a useful alternative to surgery in selected patients, say researchers from the University of Brescia in Italy.
Freezing abnormal electrical pathways in the hearts of young patients may be a safer alternative to zapping them with powerful radiofrequency probes in order to treat tachycardias and other arrhythmias, according to a new study in the April 5, 2005, issue of the Journal of the American College of Cardiology.
Endovenous laser ablation is a safe and highly effective treatment for a common but under-recognized cause of varicose veins -- reflux in a variety of veins collectively referred to as non-great saphenous veins -- according to results of a study presented today at the 30th Annual Scientific Meeting of the Society of Interventional Radiology.
Doctors prescribed different medications to control the cardiac arrhythmia, or abnormal heartbeat. But the medications slowed his heart rate too much, at times to as low as 40 beats per minute.
Interventional radiologists at Temple University Hospital now are able to treat many patients with minimally invasive procedures not available only a few years ago. “Conditions that used to require extensive surgery now take an hour or less, and patients leave with a bandaid and walk home,” says Gary Cohen, M.D., Section Chief of Interventional Radiology and Vice Chairman of Radiology. “How can you beat that?”
Researchers for Peregrine Pharmaceuticals presented today at the Strategic Research Institute’s Clinical-Stage Product Partnering Summit in La Jolla, CA a summary of clinical experience with Tumor Necrosis Therapy (TNT). The TNT technology is being developed in the U.S. and Europe by Peregrine under the trade name Cotara™. Over 200 patients have been treated with TNT world-wide and a TNT product has been approved to treat grade III or IV advanced lung cancer in the People’s Republic of China. A Cotara registration study for brain cancer has been approved by the U.S. Food and Drug Administration, and a Phase I colorectal cancer study is on-going at Stanford University Medical Center.
